To all whom 'it may, concern:

Be it known that I, CHARLES H. KNAPP, a citizen of theUnited States, residing at Chicago, 'in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Coiribi'ned Hay Rake and Elevator; and I do declare the following to be a full, clear, and exactdescripti'on of the invention, skilled in the art' to which it appertains to make and use thesame.

My invention relates' to f combined hay rakes and elevators.

The object of the invention is to provide a device' of this character which will pick up the hay in clean rows and elevate it to a point where it may be received by the hay rack or the elevator which a wagon body. l

A fi'rrtherV object. ofthe invention is the provision of means used in connection with provides for a positive dischargev of the bunches. of 'hay` at apoiiit approximately over the wagon body or hay rae Heretofore in devices ofl this character, the elevator has'been sol constructed that bunches of hay were frequently carried back to the lrake end-and often clogged the apparatus to such' anvextentlthat '1t was necessary to use force to 'clear'the parts, `and it is. theobject of -my invention to avoid 4these dfliculties and to provide'a device which will b e efficient in operation and practically automatic in its action.

Further objects will appear as the specific description is readin connection 'with the accompanying drawings which forma part iis specification, and .iii.\vl iieh,

Figure 1 is a side elevation; Fig. 2 is a top plan view; Fig. 3 is a vertical longitudinal sectionalview; Figs is a cross. sectional view taken on the line lfd of Fig. 3;

the wheel' and machine vided with Fig. 5 is a fragmentary side elevation of the partly in section and showing particularly the fork mechanism; Fig. 6 is a 6-6 of Fig. 5; Fig. 7

is a fragmentary view of the releasing mechanism in 'top plan; and Fig. 8 is a sectional view taken on line 8-8 of Fig. 7.

f Referring more especially to the drawings, 1, 2 and 3,' respectively, represent the axle, the body, of the wagon orvhayl rack, which isprovided with the usual reach, 4, extending rearwardly of the axle and proa hook, 5, adapted to be engaged by a similar hook,

such as will enable others' These wheels are loosely side members, 10. `shaft 22 I provide shaft, 26.

` Between the lugs 23 I their lower ends 6, carried by the tongue, 7 of the elevaton This tongue is bolted to a pair of transverse members, 8 and-9, which extend across and connect ythe side members, 10, of the elevator. These si de members eX- tend rearwardly and are connected by a cross beam, 111, to which is hinged -the elevator table, 12, by hinges, 13. Projecting rearwardly from the cross beam, 11, is a pair of supporting arms, 14, in which is journaled the supportin'gaxle, 15, carryin upon its outer end the traction wheels, 16. mounted uponthe axle and are provided with pawls, 17, spring pressed into engagement with ratchet wheels, 18, keyed to the shaftand connected with a bevel pinion, 19,A by a collar, 20. Each one of the gears 19 meshes with a pinion, 21, which is carried by a longitudinal shaft, 22, j ournaled in lugs, 23, which depend from the a erankarm, 24, having aslot, 25, to adjustably accommodate a s tub Journaled upon the stub shaft is a fork', 27, having its lower' end provided with a plurality of tines, 28, and its upper end slidably mounted in a guiding member, 29, adjustably journaled in bearings, 30, carried by the 'forked supporting bracket, which is in turn supported upon the side members, 32, of the conveyer table, I2.

rigidly keyed to the shaft, and extending upon either'side of the disk are the legs of a forked lever, 34, pivoted at 35 to a s||pporting membra',

have showna plate, 257, se-

with holes, 38, for the reception of an .adjusting stud, 39, carried by the upper vpart At the outer end of-this provide a disk, 3 3, i

The elevator or conveyer comprises the Side members, 32,

` by a cross slat,40, to -which the hinges, 13, are connected. Several cross slats, 41, are bridged across from side piece to side-piece, and lying thereupon are longitudinalslat's, 42, wl'iiehform the bed of the which are connected at conveyer and provide a support for the material as it passes from the receiving lend to the discharge end.

Keyed to the shaft, 1.5i, adjacent either' end thereof, is a pair of sprocket wheels, 43,

which act in conjunction with a similar pair of 4sprocket wheels, 44, adjustably'carried upon the bracket supports, 45, secured to the outer ends of the slats, 42. These bracket supports are slotted at 46, and provided with a pair of bolts having thumb nuts, 47, so that the tension of the conveyer chains, 48, may be regulated.

' At intervals throughout the length of the '15 chains I provide rcross slats, 49, which have projecting from their upper faces, tines or grasping pins, 50, adapted to enter the bunches'of hay so that the conveyer Vsecures a good grip thereupon. Each end of the slats is provided with a stub shaft, 51, which '25 chain, 43, and on the opposite side to a'ri vet ot' the chain by a tension spring, 54.

Carried at the end ot' the side members, 32,

and overhanging the. chain, 4S, and the sprocket wheels, 44, is a pair ot' semi-circu- `lar guide arms, 55. which engage with the upper portion of the arms, as they pass thereunder `and bend them down. against the tension of the spring, 54, so as to allow the chain 53 to slacken and the pins 50 to turn projecting downwardly by a s iral spring, 71, which is -secured at one en to the axle, 66, and at the other end to the rake, 67. The y'tunes of the rake are adjusted a ainst the tension of the spring by a pairof c iains, 72, which are connected to screw bolts, 73, carried by the cross beam, 62. Extending .from l'each tine of the rake,l67, are spring tin ers, 74, whichconform in shape to the out ine of the sprockets, 43, and are arranged to receive the hay as it is pickedup by the tines, and to hold it in position to be grasped by the points, 50, on the slats, 49.

It will be seen that the entire rake mechanism is independent of the conveyer mechanism and thatthe conveyer mechanism may bedisengaged from the wagon or hay rack at any desired time. To support the conveyer in its proper position when disengaged from the wagon or hay rack, I provide a supporting frame, 75, which is hinged to the forward end of the side members, 10, and is held up out of engagement with the ground by a locking hook, 7 6.

In operation the rack and conveyer arepulled along behind the wagon or rack and the pawls on the wheel engage the ratchets 18, and operate the shafts, 22, through the gear and pinion, 19 and 21. This gives arotary motion to the' crank arm, 24, and practically a rotary motion to the tines, 28, of the fork, 27. As the forks on opposite sides travel in opposite directions, it will bo seen that the hay is picked up and thrown into backwards, as shown in Figi). lVhen the the path of the rake tines, where it is re- 100 arms 52, is released from the guiding arm, ceived and rides up thereupon by the for l 55, the slats, 49, are snapped violently by the ward motion of the machine.
